Abstract

The headlamp unit has a dipped headlamp beam group with a reflector (3), a light source, a light stop and a projection lens (6) and a main headlamp beam group with a reflector (7) and a light source, the entire unit pivoted about a horizontal axis via an automatic beam width control (2). The dipped headlamp beam unit may be pivoted about a vertical axis during cornering.

Description

Die Erfindung betrifft eine Abblendlicht/Fernlicht-Scheinwerfereinheit für ein Kraftfahrzeug, wobei eine Abblendlichtgruppe aus Reflektor, Lichtquelle, Strahlenblende und Projektionslinse mit einer Fernlichtgruppe aus Reflektor und Lichtquelle kombiniert ist, mit dem Kennzeichen, daß die kombinierte Einheit mit einer automatischen Leuchtweitenregulierung zum Verschwenken der kombinierten Einheit um einer horizontale Achse gekoppelt ist.The invention relates to a low beam / high beam headlight unit for a Motor vehicle, a low beam group consisting of reflector, light source, Radiation diaphragm and projection lens with a high beam group consisting of reflector and Light source is combined, with the characteristic that the combined unit with a automatic headlight range adjustment for swiveling the combined unit is coupled about a horizontal axis.

Der Schwenkbereich der kombinierten Einheit zur Leuchtweitenregulierung ist z.B. 0,57° von der Horizontalebene nach unten für Country Light, 0,34° nach unten für Abllendlicht und in der Horizontalen für Fernlicht; automatische Gegenverkehrserfaßeinheiten, die mit Entfernungsmessung arbeiten, sind an sich bekannt und werden als adaptive cruise control units bezeichnet.The swivel range of the combined headlight range control unit is e.g. 0.57 ° down from the horizontal plane for Country Light, 0.34 ° down for Low beam and horizontal for high beam; automatic Oncoming traffic detection units that work with distance measurement are in themselves known and are referred to as adaptive cruise control units.

Bevorzugt ist dabei, daß die Abblendlichtgruppe in der kombinierten Einheit um eine Vertikalachse verschwenkbar ist. Auf diese Weise kann mit der Abblendlichtgruppe die Kurvenausleuchtung erfolgen, wobei die Verschwenkung von Scheinwerfern in Abhängigkeit vom Kurvenradius, beispielsweise radeinschlagabhängig, bekannt ist.It is preferred that the low beam in the combined unit by one Vertical axis is pivotable. In this way, the low beam group Illumination of curves take place, the pivoting of headlights in Dependence on the curve radius, for example depending on the wheel lock, is known.

Als Alternative dazu oder gegebenenfalls zusätzlich kann vorgsehen sein, daß die Abblendlichtgruppe mit einer Kurvenlichtgruppe aus einem Zusatzreflektor mit zugeordnetem Schwenkspiegel kombiniert ist, wobei der Zusatzreflektor Licht von der Abblendlichtquelle auf den Schwenkspiegel reflektiert und der Schwenkspiegel kurvenradiusabhängig angesteuert ist. Auf diese Weise kann in der Kurve ein weitaus breiteres Lichtbündel mit unveränderten Geradeausanteil und erhöhter kurveninnerer Lichtkonzentration erhalten werden.As an alternative to this, or if necessary additionally, it can be provided that the Low beam group with a cornering light group with an additional reflector assigned swivel mirror is combined, the additional reflector light from the Low beam light reflected on the swivel mirror and the swivel mirror is controlled depending on the curve radius. This way, a lot can be in the curve wider light beam with unchanged straight-ahead portion and increased inside of the curve Light concentration can be obtained.

Die Erfindung wird nachstehend anhand von zwei Ausführungsbeispielen unter Bezugnahme auf die Zeichnung näher beschrieben, in der Fig. 1 eine Stirnansicht, Fig. 2 ein Horizontalschnitt einer ersten Ausführungsform eines erfindungsgemäßen Scheinwerfers und Fig. 3 eine schaubildliche Schrägansicht von dessen Abblendlichtgruppe und Fernlichtgruppe ist sowie die Fig. 4 bis 6 entsprechende Darstellungen einer zweiten Ausführungsform sind. Gleiche Bauteile tragen gleiche Bezugszeichen.The invention is described below using two exemplary embodiments Described in more detail with reference to the drawing, in FIG. 1 an end view, FIG. 2 a horizontal section of a first embodiment of an inventive 3 and a perspective oblique view of the headlamp Low beam group and high beam group is corresponding to FIGS. 4 to 6 Are illustrations of a second embodiment. The same components carry the same Reference numerals.

In einem Scheinwerfergehäuse 1 ist eine automatische Leuchtweitenregulierung 2 angeordnet (2 bezeichnet deren Entfernungsmesser, 2' deren Steuergerät) die eine kombinierte Einheit aus einer Abblendlichtgruppe und einer Fernlichtgruppe um eine horizontale Achse verschwenkt. Die Abblendlichtgruppe besteht aus Abblendlichtreflektor 3, Abblendlichtquelle 4, Blende 5 und Projektionslinse 6; die Fernlichtgruppe besteht aus Fernlichtreflektor 7 und Fernlichtquelle 8. Bei der Ausführungsform nach den Fig. 1 bis 3 ist die Abblendlichtgruppe 3 bis 6 um eine vertikale Achse horizontal verschwenkbar.An automatic headlight range control 2 is located in a headlight housing 1 arranged (2 denotes their rangefinder, 2 'their control device) one Combined unit from a low beam group and a high beam group by one horizontal axis swiveled. The low beam group consists of Low-beam light reflector 3, low-beam light source 4, diaphragm 5 and projection lens 6; the High beam group consists of high beam reflector 7 and high beam source 8. At the Embodiment according to FIGS. 1 to 3, the low beam group 3 to 6 is one vertical axis can be swiveled horizontally.

Bei der Ausführungsform nach den Fig. 4 bis 6 ist die Abblendlichtgruppe 3 bis 6 unbeweglich, dafür aber mit einer Kurvenlichtgruppe kombiniert, die aus einem Zusatzreflektor 9 mit zugeordnetem Schwenkspiegel 10, besteht, die Licht von der Abblendlichtquelle 4 erhalten und wobei der Schwenkspiegel 10 kurvenradiusabhängig um eine Vertikalachse 11 schwenkbar ist. In Fig. 6 ist der Antrieb für den Schwenkspiegel 10 mit 12 bezeichnet.In the embodiment according to FIGS. 4 to 6, the low beam group is 3 to 6 immovable, but combined with a cornering light group consisting of one Additional reflector 9 with associated swivel mirror 10, which is the light from the Low beam source 4 obtained and the pivoting mirror 10 depending on the curve radius is pivotable about a vertical axis 11. 6 is the drive for the Swivel mirror 10 designated 12.

Bei den beiden Ausführungsformen bezeichnet jeweils 13 das Begrenzungslicht und 14 die Richtungsanzeige.In the two embodiments, 13 denotes the marker light and 14 the direction indicator.

Die Abblendlichtgruppe ist zweckmäßig mit einer D2S oder D2R Lichtquelle, die Fernlichtgruppe mit einer H7 Lichtquelle ausgerüstet. Gegebenenfalls kann ein kleiner Zusatzreflektor zum Erkennen von Überkopfstraßenbeschilderungen vorgesehen sein, der oberhalb des Gegenverkehrblendbereichs abstrahlt.The low beam is useful with a D2S or D2R light source High beam group equipped with an H7 light source. If necessary, a small one Additional reflector for recognizing overhead street signs can be provided, that emits above the oncoming traffic glare area.
